Ultrasonic method for residual stress characterization — Part 1: Critically refracted longitudinal wave ISO/PWI 25148-1

Scope

This document specifies the test method for measuring residual stress by using ultrasonic critical refracted longitudinal wave.
This document is applicable to metallic and non-metallic solid materials which have a good acoustic permeability to determine residual or loading stresses non-destructively.
